Perhaps they genuinely don't rate the game? Do you have any particular reason to think that Jaguar is an impatient, arrogant asshole, or do you just not agree with his opinion and are enough of an arrogant asshole to lay into him for this?

It sucks for a developer who has worked hard on a title to see their work get slammed but perhaps their work deserves to be slammed. It must also suck to be a critic when you routinely get accused of being publishers' bitches, yet when they call it as they see it they get more stick.
